1. The board is a single-channel power amplifier board, which requires dual-channel
2. The circuit design uses A970/C2240 high-voltage audio pair tube dual differential circuit and A1145/C2705 for voltage amplification to promote the use of mid-power pair tube A1837/C4793, and the output stage uses A1943/C5200 high-power Toshiba pair tube.
3.Wide power supply range, DC plus or minus 20V-90V can be, as long as enough power is supplied to easily reach 200, the sound quality is good, the driving force is strong, and the 15-inch speaker is pushed without pressure!
4. Power supply: dual voltage, DC plus or minus 20-90V (the upgraded version has optimized the circuit and parts, but To directly apply high voltage, it is recommended to use below 90V, do not challenge the voltage limit. )
5. Real power: undistorted power 200W, maximum power 300W.
